工业散热器的热阻系数

  不知道大家对工业散热器热阻系数的了解有多少,了解的不多也没关系,下面就给大家具体的介绍一下,希望大家仔细阅读。
  
  工业散热器的传递单位热量所需要的温差越大,其热阻就会变得越大,其热阻等于换热系数的倒数,说明换热系数越大,其热阻越小,反之,换热系数越小,其热阻就越大。空气侧的换热系数小于水侧的换热系数,因而空气侧的热阻大于水侧的热阻,成为了影响传热的主要热阻,使得空气侧成为了传热过程的瓶颈,限制了传热量的提高。为了减小空气侧的热阻,克服空气侧瓶颈效应,可能采取多种措施,选择就是在空气侧外表面增加翅片,即采用翅片管。翅片管使空气侧原有的换热面积有了很大扩展,弥补了空气侧换热系数低的特点,使传热量大大提高。
  
  上面是为大家整理的工业散热器知识,希望能够得到大家的认可,如果大家还有什么要补充的请随时联系我们,谢谢!
